SilenX Ixtrema Pro 40x40x10mm 12 Volt Fan IXP-11-14

Patent pending Fan with Dynamic Bearings. Extremely quite. Results show this fan pushes more air at a slower speed giving it a quiet air flow not obtained by competing older style fan.

The former gold standard in airflow to noise ratio, iXtrema Pro Quiet Fans are the only fans in the industry to be designed with silence and optimal airflow in mind. Smaller, domed motor hub, larger, more dramatic fan blade sweep area, they offer unrivaled performance along with a noise characteristic that makes it a favorite among professionals. There might be fans that offer more airflow or lower noise levels, but when it comes to a balance between the two, these fans can't be beat, especially with fluid dynamic bearings for ultra long life and reduced vibration.
